5G, or fifth-generation wireless technology, is a wireless communication system designed to provide faster speeds and lower latency to more users and improve network efficiency.  Once available globally, wireless communication systems will transform industries such as healthcare, protain and transport ideology and expand the technologies and applications available to smart cities around the world.

What is 5G wireless communication?

5G brings a wealth of new features, including reduced latency, enhanced data speeds, increased network capacity, and improved network efficiency.  5G networks are created to offer faster download speeds of approximately up to 20Gbps  . offered by 4G networks.

Latency across the 5G network is also improved and can be reduced to 1 millisecond instead of the 30-50 milliseconds offered by 4G.  This lower latency will provide a critical step towards enabling new applications that require real-time communication.

In addition to lower latency, 5G networks can also handle more devices at the same time, allowing more users and devices to connect to the network, so that IoT sensors, self-driving vehicles and other robotic devices can be connected to the 5G network at the same time. Growing demand for wireless connectivity in densely populated areas, growth in large-scale IoT deployments.

5G networks also improve network efficiency with advanced technologies such as beamforming, which is used to focus wireless signals in specific directions, improving signal quality and reducing interference.

When integrated into 5G networks, beamforming is able to optimize the wireless signal for each user, significantly improving their network performance. Other technologies used by 5G include massive MIMO, which allows the use of multiple antennas at the transmitter and receiver to improve network capacity, coverage and signal quality.

Another key technology for 5G is millimeter wave (mmWave) spectrum, enabling 5G to use millimeter wave (mmWave) spectrum at 24GHz and above. Provides more bandwidth and allows for faster data speeds and increased capacity. Although mmWave signals have a shorter range and are easily blocked by buildings and other obstacles, 5G networks use small cell technology, massive MIMO and beamforming to overcome these limitations. Small cells are low-power base stations that can be installed in urban areas to improve network coverage and capacity.

The difference between 5G and 4G

Successive generations of wireless communication technologies have been rolled out, first 3G, then 4G, and now 5G is being touted as the latest wireless technology, offering faster data speeds, lower latency and higher network capacity. While both 4G and 5G were created to provide us with faster, more reliable mobile connections, they differ significantly in speed, latency, capacity, and network architecture. Listed below are just some of the differences between 5G and 4G.

1. Compared with the older generation of 4G network architecture that adopts technologies such as edge computing and network function virtualization (NFV), the network architecture of 5G has a more flexible and scalable system. Provide users with faster and more efficient data processing to reduce our reliance on the centralized infrastructure used by previous generations of 3G and 4G.

2. The new 5G network was created to provide greater efficiency than previous 4G using technologies such as network slicing, massive MIMO, and beamforming. It enables operators to allocate resources easily and more efficiently while improving signal quality, and provides various customized services according to the needs of different users and industries.

3.5G networks have higher capacity than 4G networks, allowing them to support more simultaneous connections, making them ideal for densely populated urban areas or sporting events, where more connections will be made by phone users as well as IoT sensors and devices .

4.5G offers lower latency, allowing data to travel faster between two points, and is capable of delivering sub-1 millisecond latency, compared to the average latency of around 30-50 milliseconds on older generation 4G networks. Latency is important for applications that require real-time communication, such as self-driving cars, remote surgery, and virtual reality applications.

Even with these amazing new improvements to 4G networks, the transition from 4G to 5G will still be gradual, and the two wireless networks will co-exist for years to come.
